Answer:

$y=0.46591x+7.71591$

Step-by-step explanation:

Labelled points are $(21,\: 17.5)=(x_1,\:y_1) \: \&\:(43,\: 27.75)=(x_2,\:y_2)$

Slope of line (m) $=\frac{27.75-17.5}{43-21} =\frac{10.25}{22} =\frac{41}{88}$

Equation of line in point - slope form is given as:

$y-y_1 = m(x-x_1)$

$\therefore y-17.5= \frac{41}{88} (x-21)$

$\therefore y= \frac{41}{88} x-\frac{861}{88}+17.5$

$\therefore y= \frac{41}{88} x+17.5-\frac{861}{88}$

$\therefore y= \frac{41}{88} x+\frac{1,540-861}{88}$

$\therefore y= \frac{41}{88} x+\frac{679}{88}$

$\therefore y=0.465909091x+7.71590909$

$\therefore y=0.46591x+7.71591$

The equation of a line is<br> -2x+5t=-20 <br>what is the x-intercept of the line?

vampirchik [111]

The x intercept of the line is at x = 10.

The x intercept is always the value of x when all other values are equal to 0. So in this case, we put 0 in for t and then solve.

-2x + 5t = -20

-2x + 5(0) = -20

-2x = -20

x = 10

A marble is randomly selected from a bag. The probability of selecting a marble with dots on it is 0.2. The probability of selec

marin [14]

Answer:

0.5

Step-by-step explanation:

Let D be the event of selecting a marble with dots.

Let P be the event of selecting a purple marble.

The probability of selecting a marble with dots, P(D)=0.2

The probability of selecting a marble that is both purple and has dots, $P(D \cap P)=0.1$

We want to determine the probability of selecting a purple marble given that the marble has dots on it, P(P|D)

By the definition of conditional probability:

$P(P|D)= \dfrac{P(P \cap D)}{P(D)} \\= \dfrac{0.1}{0.2}\\ =0.5$

The probability of selecting a purple marble given that the marble has dots on it is 0.5.
